This is a basic, 4-digit 7-segment display - white in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points.
The LEDs have a forward voltage of 1.9VDC and a max forward current of 20mA. The hardware interface is sixteen (two rows of eight) through-hole pins
The datasheet for this device says "blue" but that's because the white display is simply a blue display with a colored film over it.
We carry this same display in yellow, green, red, and blue.
